Abstract

Methods and apparatus for estimating the state and parameters of an electrochemical cell. More particularly, for example, a method for estimating present states and present parameters of an electrochemical cell system comprising: estimating a state value of the electrochemical cell with a cell state filter to estimate the state value; estimating a parameter value of the electrochemical cell with a cell parameter filter to estimate the parameter value, and exchanging information between the cell state filter and the cell parameter filter. Also an apparatus configured to estimate present states and present parameters of an electrochemical cell comprising: a first component configured to estimate a cell state value; and a second component configured to estimate a cell parameter value. The first component and second component are in operable communication to exchange information there between.
